I despise Birth-Control first because it is ... an entirely meaningless word; and is used so as to curry favour even with those who would first recoil from its real meaning. The proceeding these quack doctors recommend does not control any birth.
Science is a wonderful thing if one does not have to earn one's living at it. One should earn one's living by work of which one is sure one is capable. Only when we do not have to be accountable to anybody can we find joy in scientific endeavor.
The spark of a genius exists in the brain of the truly creative man from the hour of his birth. True genius is always inborn and never cultivated, let alone learned.
If in a discussion of many matters ... we are not able to give perfectly exact and self-consistent accounts, do not be surprised: rather we would be content if we provide accounts that are second to none in probability.
All the fifty years of conscious brooding have brought me no closer to answer the question, "What are light quanta?" Of course today every rascal thinks he knows the answer, but he is deluding himself.
This is the patent-age of new inventions For killing bodies, and for saving souls, All propagated with the best intentions; Sir Humphrey Davy's lantern, by which coals Are safely mined for in the mode he mentions, Tombuctoo travels, voyages to the Poles, Are ways to benefit mankind, as true, Perhaps, as shooting them at Waterloo.
[Science] is not perfect. It can be misused. It is only a tool. But it is by far the best tool we have, self-correcting, ongoing, applicable to everything. It has two rules. First: there are no sacred truths; all assumptions must be critically examined; arguments from authority are worthless. Second: whatever is inconsistent with the facts must be discarded or revised. ... The obvious is sometimes false; the unexpected is sometimes true.
PROBOSCIS, n. The rudimentary organ of an elephant which serves him in place of the knife-and-fork that Evolution has as yet denied him. For purposes of humor it is popularly called a trunk.
Poetry is not the proper antithesis to prose, but to science. Poetry is opposed to science, and prose to meter. The proper and immediate object of science is the acquirement, or communication of truth; the proper and immediate object of poetry is the communication of immediate pleasure.
Modern science is necessarily a double-edged tool, a tool that cuts both ways. ... There is no doubt that a Zeppelin is a wonderful thing; but that did not prevent it from becoming a horrible thing.
[George] Uhlenbeck was a highly gifted physicist. One of his remarkable traits was he would read every issue of T%he Physical Review from cover to cover.
Man is a little germ that lives on an unimportant rock ball that revolves about a small star at the outskirts of an ordinary galaxy. ... I am absolutely amazed to discover myself on this rock ball rotating around a spherical fire. It's a very odd situation. And the more I look at things I cannot get rid of the feeling that existence is quite weird.
We come no nearer the infinitude of the creative power of God, if we enclose the space of its revelation within a sphere described with the radius of the Milky Way, than if we were to limit it to a ball an inch in diameter. All that is finite, whatever has limits and a definite relation to unity, is equally far removed from the infinite... Eternity is not sufficient to embrace the manifestations of the Supreme Being, if it is not combined with the infinitude of space.
One should not understand this compulsion to construct concepts, species, forms, purposes, laws ('a world of identical cases') as if they enabled us to fix the real world; but as a compulsion to arrange a world for ourselves in which our existence is made possible:-we thereby create a world which is calculable, simplified, comprehensible, etc., for us.
